This is why many are also taking advantage of the telegram groups by displaying themselves and disguising as the admin's, there's no way to stop this but to give public awareness.
There are also scammers on twitter.
Just like by visiting those announcements from the developers, there are these like giveaways that are being held through that.
When there is some instructions that dictates to send you xx amount of eth or bitcoin to an address, that's an obvious scam.
There are many scammers like that and they are everywhere so the only thing we can do to protect ourselves is to not be so dumb, scammers are very smart somehow they are able to get the list of everyone that invested in an ico and then they send them malicious emails trying to get their private keys and unfortunately many people fall for it, so people need to familiarize themselves with the current scams so they can avoid it.
Out of their laziness their natural intelligence is coming out in everything that becomes popular, they are creating a way to scam people.
And about those malicious emails, it's been in old days that there are so many email scams that are coming out.\
Now they have upgraded into cryptocurrency so as a protection, don't expose any information relevant to your identity because it can be used against you by these scammers.
It is true that the scammers are becoming more advanced but I think that they're still making use of the old formulas and if people are not able to protect themselves from those attacks then how are they going to protect themselves for the new attacks of the scammers and the hackers, also it is a good idea to try to not open any links that are sent to you through social media because most of the time that includes some kind of virus that can compromise your information.
